Description

Vanne à commande pneumatique Pneumatically operated valve
La présente invention concerne une vanne à commande pneumatique destinée à assurer la distribution de fluides de toute nature, compressibles ou non, pouvant atteindre des températures élevées, notamment en vue d'applications dans l'industrie agro-alimentaire (stérilisation par exemple) et dans les processus industriels.The present invention relates to a pneumatically controlled valve intended to ensure the distribution of fluids of all kinds, compressible or not, capable of reaching high temperatures, in particular for applications in the food industry (sterilization for example) and in industrial processes.
Le problème technique résolu par la présente invention est celui de la conception d'une vanne compacte, de faible encombrement, permettant de réaliser des assemblages de vannes identiques, positionnées les unes à côté des autres par juxtaposition, de manière que l'encombrement en largeur de ces assemblages ne dépasse pas l'encombrement en largeur des conduites respectives d'alimentation et d'évacuation des vannes qui les constituent.The technical problem solved by the present invention is that of the design of a compact, compact valve, making it possible to produce identical valve assemblies, positioned side by side by juxtaposition, so that the overall width of these assemblies does not exceed the overall dimensions in width of the respective supply and discharge pipes of the valves which constitute them.
En conséquence, la présente invention concerne une vanne à commande pneumatique comportant un piston de commande à rappel par ressort auquel est attelé un organe d'obturation des voies d'admission et d'échappement prévues dans le corps d'actionneur, caractérisée en ce que ledit piston de commande présente une section droite elliptique, son grand axe étant situé dans le même plan que l'axe des conduites d'admission et d'évacuation du fluide véhiculé par la vanne et la longueur de son petit axe étant choisi de façon que la largeur dudit corps d'actionneur ne dépasse pas la valeur d'encombrement des éléments de. raccordement des conduites auxquelles ladite vanne est raccordée.Consequently, the present invention relates to a pneumatically controlled valve comprising a spring-return control piston to which is attached a shutter member for the intake and exhaust paths provided in the actuator body, characterized in that said control piston has an elliptical cross section, its major axis being located in the same plane as the axis of the inlet and outlet pipes of the fluid conveyed by the valve and the length of its minor axis being chosen so that the width of said actuator body does not exceed the overall value of the elements. connection of the pipes to which said valve is connected.
Selon une autre caractéristique de la présente invention, le joint qui assure l'étanchéité entre le piston de commande et le corps d'actionneur est monté statique dans un logement ménagé dans ledit corps d'actionneur. D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après en référence aux dessins annexés qui en illustrent divers exemples de réalisation dépourvus de tout caractère limitatif. Sur les dessins : - les figures 1 et 2 sont des vues en coupe axiale verticale de deux exemples de réalisation d'une vanne selon l'invention ;According to another characteristic of the present invention, the seal which seals between the control piston and the actuator body is mounted statically in a housing formed in said actuator body. Other characteristics and advantages of the present invention will emerge from the description given below with reference to the accompanying drawings which illustrate various embodiments thereof which are in no way limiting.

FIGS. 10a to 10c are respectively perspective views, in side elevation and in plan, of a valve assembly according to the invention, in the “distribution island” configuration and
- les figures 11a à 11c sont respectivement des vues en perspective, en élévation latérale et en plan d'un autre assemblage de vannes selon l'invention, également en configuration « îlot de distribution « .- Figures 11a to 11c are respectively perspective views, in side elevation and in plan of another assembly of valves according to the invention, also in "distribution island" configuration.
En se référant aux dessins, on voit que la vanne à commande pneumatique selon l'invention comporte comme connu un corps d'actionneur 10 dans lequel est monté un piston de commande 1 sur lequel agit la pression de commande et qui est rappelé par un ressort, ce piston étant prolongé par une tige de commande 2 portant à son extrémité l'organe d'obturation 3 des voies d'admission et d'échappement de la vanne, respectivement 4 et 5. Selon la présente invention, le piston de commande 1 présente une section elliptique ainsi qu'on le voit clairement sur la figure 3. Le grand axe de cette ellipse est situé dans le même plan que l'axe des conduites 4' et 5' sur lesquelles sont raccordées respectivement les voies 4 et 5 de la vanne et la longueur du petit axe de l'ellipse est choisie de manière que la largeur L du corps d'actionneur 10 ne dépasse pas la valeur du diamètre desdites conduites 4' et 5' et de leurs éléments de raccordement 6 et 7 audit corps (voir les figures 7 et 8 sur lesquelles on reviendra ci-après). Grâce à cette caractéristique, on diminue dans des proportions importantes l'encombrement en largeur de la vanne par rapport aux vannes selon l'état antérieur de la technique qui possèdent un piston de commande à section circulaire.Referring to the drawings, it can be seen that the pneumatic control valve according to the invention comprises, as known, an actuator body 10 in which is mounted a control piston 1 on which the control pressure acts and which is returned by a spring , this piston being extended by a control rod 2 carrying at its end the shutter member 3 of the inlet and outlet paths of the valve, respectively 4 and 5. According to the present invention, the control piston 1 has an elliptical section as can be clearly seen in FIG. 3. The major axis of this ellipse is located in the same plane as the axis of the pipes 4 'and 5' on which are connected respectively the tracks 4 and 5 of the valve and the length of the minor axis of the ellipse is chosen so that the width L of the actuator body 10 does not exceed the value of the diameter of said pipes 4 'and 5' and their connection elements 6 and 7 to said body (see FIGS. 7 and 8 to which we will return below). Thanks to this characteristic, the overall dimensions of the valve are reduced in significant proportions compared to the valves according to the prior art which have a circular section control piston.
L'organe d'obturation 3 peut être du type à membrane comme illustré par les figures 1 et 3. Dans cet exemple de réalisation non limitatif, la membrane de l'organe d'obturation contribue en outre à assurer l'étanchéité entre le corps d'actionneur 10 et la tige de commande 2, comme on le voit clairement sur la figure 1 où la vanne a été représentée en position fermée.The shutter member 3 may be of the membrane type as illustrated in FIGS. 1 and 3. In this nonlimiting exemplary embodiment, the membrane of the shutter member also contributes to ensuring the seal between the body actuator 10 and the control rod 2, as clearly seen in Figure 1 where the valve has been shown in the closed position.
Dans l'exemple de réalisation représenté sur les figures 2, 4 et 5, l'organe d'obturation 3 est réalisé sous la forme d'un clapet en forme de piston qui est encastré dans un logement prévu à l'extrémité de la tige de commandeIn the embodiment shown in Figures 2, 4 and 5, the shutter member 3 is made in the form of a piston-shaped valve which is embedded in a housing provided at the end of the rod control
2. Dans cette variante, l'étanchéité entre la tige de commande 2 et le corps d'actionneur 10 est assurée par un système de joint 8 (figures 4 et 5).2. In this variant, the seal between the control rod 2 and the actuator body 10 is ensured by a seal system 8 (Figures 4 and 5).
Le pilotage du piston de commande 1 s'effectue depuis la partie supérieure du corps d'actionneur, les circuits de pilotage étant prévus dans le corps 10. Sur les figures 4-8, on a . désigné par les références 11 et 11 ' les orifices de pilotage débouchant sur la surface supérieure du corps 10, les circuits de pilotage internes n'étant pas visibles sur les dessins. Selon l'invention, la face supérieure du corps 10 peut être aménagée en plan de pose pour une électrovanne de pilotage, ce plan de pose pouvant être bien entendu normalisé. Selon une autre caractéristique de cette invention, le joint 9 assurant l'étanchéité entre le corps d'actionneur 10 et le piston de commande 1 est monté dans un logement prévu dans ledit corps 10 ainsi qu'on peut le voir, notamment sur les figures 1 et 2. Grâce à cette caractéristique, le joint 9 qui est statique dans son logement assure une double fonction d'étanchéité, d'une part sur le corps 10, et d'autre part sur le piston 1.The control of the control piston 1 is carried out from the upper part of the actuator body, the control circuits being provided in the body 10. In FIGS. 4-8, we have. designated by the references 11 and 11 ′ the pilot orifices opening onto the upper surface of the body 10, the internal pilot circuits not being visible in the drawings. According to the invention, the upper face of the body 10 can be arranged in a laying plane for a piloting solenoid valve, this laying plane can of course be standardized. According to another characteristic of this invention, the seal 9 ensuring the seal between the actuator body 10 and the control piston 1 is mounted in a housing provided in said body 10 as can be seen, in particular in the figures 1 and 2. Thanks to this characteristic, the seal 9 which is static in its housing provides a double sealing function, on the one hand on the body 10, and on the other hand on the piston 1.
La vanne selon l'invention peut être du type « normalement ouverte » ou du type « normalement fermée ».The valve according to the invention can be of the “normally open” type or of the “normally closed” type.
Dans l'exemple de réalisation illustré par la figure 1 , lorsque la vanne doit être du type normalement ouverte, le ressort de rappel est disposé dans l'alésage 12 et il exerce son effort de rappel sur la face inférieure du piston 1 (ce ressort n'a pas été représenté) et la pression de commande s'exerce sur la face supérieure du piston 1 à partir de la chambre 13 alors que, lorsque la vanne est du type normalement fermée, le ressort de rappel est disposé dans la chambre 13 et exerce son action sur la face supérieure du piston, et la pression de commande qui s'exerce sur la face inférieure du piston 1 est admise dans l'alésage 12.In the embodiment illustrated in FIG. 1, when the valve must be of the normally open type, the return spring is placed in the bore 12 and it exerts its return force on the underside of the piston 1 (this spring has not been shown) and the control pressure is exerted on the upper face of the piston 1 from the chamber 13 whereas, when the valve is of the normally closed type, the return spring is disposed in the chamber 13 and exerts its action on the upper face of the piston, and the control pressure which is exerted on the lower face of the piston 1 is admitted into the bore 12.
Les mêmes configurations et fonctions peuvent être obtenues avec l'exemple de réalisation illustré par la figure 2. En version normalement ouverte, le ressort de rappel est disposé dans l'alésage 12 et la pression de commande s'exerce sur la face supérieure du piston 1 à partir de la chambre 13, alors qu'en version normalement fermée, le ressort de rappel est logé dans la chambre 13 et la pression de commande s'exerce sur la face inférieure du piston à partir de l'alésage 12.The same configurations and functions can be obtained with the embodiment illustrated in FIG. 2. In the normally open version, the return spring is disposed in the bore 12 and the control pressure is exerted on the upper face of the piston 1 from chamber 13, while in the normally closed version, the return spring is housed in chamber 13 and the control pressure is exerted on the underside of the piston from bore 12.
Sur les variantes illustrées aux figures 4 et 5, on retrouve les caractéristiques de la vanne représentée sur la figure 2. On y voit les ressorts de rappel 14 et 15 correspondant respectivement aux versions « vanne normalement fermée » (figure 4) et « vanne normalement ouverte » (figure 5). Cependant dans cette variante, la pression de commande s'exerce toujours dans la chambre recevant le piston de commande 1 , celle-ci étant séparée en deux enceintes distinctes et indépendantes 16 et 17, par le piston 1.On the variants illustrated in Figures 4 and 5, we find the characteristics of the valve shown in Figure 2. We see the return springs 14 and 15 corresponding respectively to the versions "valve normally closed" (Figure 4) and "valve normally open ”(Figure 5). However, in this variant, the control pressure is always exerted in the chamber receiving the control piston 1, the latter being separated into two separate and independent chambers 16 and 17, by the piston 1.
En version normalement fermée (figure 4), la pression de commande est admise dans la chambre inférieure 17 et elle s'exerce sur la face inférieure du piston 1 à rencontre de l'action du ressort 14 alors que, dans la version normalement ouverte (figure 5), la pression de commande est admise dans la chambre supérieure 16 de façon qu'elle s'exerce sur la face supérieure du piston à encontre de l'action du ressort 15.In the normally closed version (Figure 4), the control pressure is admitted into the lower chamber 17 and it is exerted on the underside of the piston 1 against the action of the spring 14 whereas, in the normally open version ( FIG. 5), the control pressure is admitted into the upper chamber 16 so that it is exerted on the upper face of the piston against the action of the spring 15.
Parmi les avantages apportés par l'invention, le plus important est celui d'un encombrement réduit résultant de la section elliptique de son piston de commande qui permet de réaliser ainsi qu'on l'a vu, une vanne dont la largeur extérieure n'excède pas la valeur de l'encombrement des éléments de raccordement des conduites auxquels elle est reliée.Among the advantages brought by the invention, the most important is that of a reduced bulk resulting from the elliptical section of its control piston which makes it possible to realize as we have seen, a valve whose external width does not not exceed the size of the dimensions of the connection elements of the pipes to which it is connected.
Cette compacité apparaît clairement de l'examen de la figure 6 qui illustre un mode de réalisation qui correspond à celui des figures 1 et 2 et dans lequel on distingue la partie commande pneumatique 10a et la partie distribution 10b du corps d'actionneur. Dans la variante, illustrée par les figures 4 et 5, les parties commande et distribution de la vanne sont intégrées dans un corps d'actionneur 10 ayant sensiblement la forme d'un parallélépipède rectangle de façon à obtenir un corps monobloc.This compactness appears clearly from the examination of FIG. 6 which illustrates an embodiment which corresponds to that of FIGS. 1 and 2 and in which a distinction is made between the pneumatic control part 10a and the distribution part 10b of the actuator body. In the variant, illustrated by FIGS. 4 and 5, the control and distribution parts of the valve are integrated in an actuator body 10 having substantially the shape of a rectangular parallelepiped so as to obtain a one-piece body.
Dans toutes les versions, il est possible de réaliser des assemblages de vannes identique par juxtaposition côte à côte dans un encombrement minimal contrairement à ce qu'il est possible de réaliser avec des vannes classiques à piston de commande à section circulaire. Les figures 7 à 11c font clairement ressortir cet avantage et l'aspect particulièrement compact des ensemble ainsi réalisés. Comme on le voit sur les figures 10a à 11c, la compacité des vannes objet de la présente invention permet de réaliser une construction du type « îlot de distribution » avec une arrivée unique et des sorties multiples :In all versions, it is possible to produce identical valve assemblies by juxtaposition side by side in a minimal space unlike what it is possible to achieve with conventional control piston valves with circular section. Figures 7 to 11c clearly highlight this advantage and the particularly compact appearance of the assemblies thus produced. As can be seen in FIGS. 10a to 11c, the compactness of the valves which are the subject of the present invention makes it possible to produce a construction of the “distribution island” type with a single inlet and multiple outlets:
- dans la variante illustrée par les figures 10a à 10c, les corps juxtaposables sont fixés les uns sur les autres et ils comportent chacun un orifice de sortie et- in the variant illustrated by FIGS. 10a to 10c, the juxtaposable bodies are fixed to one another and they each have an outlet orifice and
- dans l'autre variante illustrée par les figures 11a à 11c, les corps juxtaposables également fixés les uns aux autres comportent chacun une sortie avec une arrivée unique.- In the other variant illustrated by FIGS. 11a to 11c, the juxtaposable bodies also fixed to each other each have an outlet with a single inlet.
Il demeure bien entendu que cette invention n'est pas limitée aux exemples de réalisation décrits et/ou représentés, mais qu'elle en englobe toutes les variantes. It remains to be understood that this invention is not limited to the embodiments described and / or shown, but that it encompasses all variants thereof.
